Hoodia Gordonii:

The level of sugar in your blood goes up when you eat, when a certain level is reached, your synapses in your brain send signals to you that you are full. Hoodia is a lot more active than glucose. It travels to the mid-brain and makes your nerve cells signal that you are full even if you haven't actually eaten. Nor will you want to.

Chitosan:

Chitosan, derived from shellfish, to bind to the fat and cholestrol in your food before your body has a chance to absorb it. Chitosan itself cannot be digested, and the body simply eliminates the Chitosan and the fat mass attached to it.
